摘要： A liquid crystal display is provided which comprises front and rear panels, and electrodes, polarizers and a layer of liquid crystal disposed between the front and rear panels. The polarizer on the rear panel is preferably a reflecting type in at least one region of the spectrum and contains at least one element in the formof a multilayer structure. The multilayer structure contains at least two anisotropic layers separated by at least one intermediate layer which is optically transparent in the desired spectral region. The ratio of refraction indices and thickness of the layersin the multilayer structure is chosen such to provide an extremumfor the ratio of the transmitted and reflected polarized light inthe spectral region.

摘要： The herein invention pertains to devices for presenting information in particular elements of liquid crystal displays, and is aimed at creating a multilayer plate, which may be used in the manufacture of liquid crystal displays, as well as at devising a design of displays with internal polarizers. The technical result of the disclosed invention is the increase of reliability and decrease of thickness of the display, as well as lowering of the manufactuing costs, an increase of useful yield and lowering the number of manufactuing operations in the process of display assembly. Technical result is achieved by the fact that the multilayer plate comprises optically transparent substrate (6), protective layer (3), conducting layer, and also at least on elayer of anisotropic membranous crystal (2). Moreover, membranous crystal (2) is formed out of material, which contains aromatic rings and has Braggpe ak at 3.4 ± 0.2 Augstrom (=0.34+0.02 nm) a long one of the optical axes. Besides that, the disclosed technical result is achieved by the fact that the display panel comprises optically transparent substrate (6), protective layer (3), system of electrodes (7), and also at least one layer of membranous crystal.

摘要： The invention pertains to devices for presenting information, in particular liquid crystal (LC) displays and may be used in indicatory technology of various purposes. Liquid crystal display, according to the invention, comprises a layer of liquid crystal (2), situated between two plates (3), on each of which there have been placed or formed electrodes (4) and at least one polarizer layer (5), while the electrodes on at least one of the plates are made transparent, and at least one layer of at least one polarizer formed on the inner side of the transparent electrodes on at least one of the plates in the display is the E-type polarizer and made out of at least partially crystalline film of molecularly ordered structure of an organic dye. Situated above the transparent electrodes, local areas of at least one layer of E-type polarizer, formed on the inner side of the transparent electrodes, are modified to enhance their conductivity.

摘要： The invention pertains to the methods of obtaining anisotropic crystalline films and to devices for carrying out the methods. A colloidal system with anisometric particles is applied as a film onto the surface of a substrate (1) while the viscosity of the colloidal system is lowered. The particles of the colloidal system with lowered viscosity are oriented and the original viscosity of the colloidal system is restored. The film is then dried. The drying is carried out under controlled conditions. Zones of the dried film may be progressively heated to improve the film characteristics.
